How to get Amanda and tape libraries to work?
Been reading docs and working on understanding amanda for about two weeks
now and finally got it up and running with a tape jukebox/library; SORTOF.
I can load/unload/label tapes in the library, and got a valid 'changer.conf',
'disklist', etc.
However cannot get amanda and the 'tpchanger' chg-zd-mtx to backup any disk
that is larger than the size of one tape in the library. Sort of defeats the
whole purpose of using amanda and tape libraries.
Plus no data is written to the disk cache, '/var/tmp', either when tape
drive fails for whatever reason, as advertised in the amanda docs.
There is tons of documentation on amanda, but I have yet to find a single
occurrence of how to get amanda to backup large disk mounts to a library and
automatically change tapes as it needs to. Let alone why no data is being
written to the disk cache, for later writing to the tape when tape errors
occur.
Now I am not even sure amanda even was designed to do so.
Has anyone on the list ever gotten amanda and tape libraries to work? Or
should I look at ufsdump and fsbackup instead?
